Practice Problems
Try them, get help one step at a time, then print how it went.
Practice: try it, then get help one step at a time
Build the constraint, read the region, count the dots, and check two limits at once. Hint gives a nudge, Show next step shows one worked step at a time, Reveal answer checks, and Hide help / start over clears the card.
My results
Finished the practice? Print a page that shows each question, what you typed or chose, the correct answer, and how it went. Good for showing a teacher or keeping in a folder.
Exit ticket
On paper or an index card. Use the math word and the plain-English word.
- Pens cost $2 and notebooks cost $3; you can spend at most $18. Write the constraint.
- For that constraint, is 3 pens and 4 notebooks allowed? 6 pens and 3 notebooks?
- Why is the answer to a hot dog and drink budget really a set of dots?
- What happens when a story has two limits at once?

- 2x + 3y ≤ 18.
- (3, 4): 6 + 12 = 18 ≤ 18, allowed, exactly on the boundary. (6, 3): 12 + 9 = 21, not allowed.
- You can only buy whole hot dogs and whole drinks, so only whole-number points in the region are real combinations.
- Shade both regions; the allowed combinations are where they overlap. That is Unit 6.
